Overhead Line Mast Stabilization via Anchor Cables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing overhead line devices for high-voltage systems are bulky and unsightly, with masts that are wide and voluminous to ensure stability, and often have unreliable conductor cable fixation, which affects landscape integration and functional reliability.
Innovation Solution
The use of anchor cable arrangements with multiple anchor cables, connected to masts and anchored underground, stabilizing conductor cables transversely and allowing for narrower, more filigree mast designs through a tensioned stabilization cable between masts, which acts as a pressure support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If masts are made wide and voluminous to ensure stability and flexural rigidity, then mast stability is improved, but landscape integration deteriorates
Solution Approach 1:
The stabilization system is segmented into multiple independent anchor cable arrangements, each with multiple anchor cables. This distributes the stabilization function across separate elements rather than requiring a single bulky mast structure, allowing the mast to be narrower while maintaining stability through the distributed anchor system.
Solution Approach 2:
The invention transitions from relying on mast cross-sectional dimensions for stability to using spatially distributed anchor cables extending into the ground. This moves the stabilization mechanism from a two-dimensional mast cross-section to a three-dimensional anchor system, enabling narrower masts with adequate stability.
2Ease of manufacture
If conventional mast designs are used with direct conductor cable suspension, then installation is simpler, but functional reliability of conductor cable fixation deteriorates
Solution Approach 1:
Anchor cable arrangements serve as intermediary elements between the masts and conductor cables. These intermediaries provide reliable fixation points for conductor cables while maintaining the simplicity of the overall installation process, resolving the contradiction between installation ease and fixation reliability.
3Device complexity
If single anchor cable arrangements are used, then device complexity is reduced, but stability of conductor cable fixation deteriorates
Solution Approach 1:
Multiple anchor cables are merged into a single anchor cable arrangement that works together to stabilize conductor cables. This combining approach enhances fixation stability while managing device complexity through integrated design of the anchor cable arrangements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration reduces mast volume and width, enhances conductor cable fixation reliability, improves landscape integration, and simplifies and reduces the cost of installation, making the system more acceptable and easier to approve.
Implementation Method 1
an anchor cable arrangement connected with its upper end to the associated mast and fixed or anchored with its lower end in a subsurface or in the ground
Implementation Method 2
a stabilization cable running between the masts and tensioned between the masts, reducing the deflection of the masts in the line direction

AI summary
The device has towers (1), and conductor ropes (2) i.e. phase cables, running along the device. The towers are stabilized with an anchor rope arrangement (3) that is oriented diagonal to the towers, where an upper end of the arrangement is connected to the towers. A lower end of the arrangement is fixed and/or anchored to a ground. The conductor ropes running perpendicular to the arrangement are supported by the arrangement and/or fixed to the arrangement. The arrangement has anchor ropes (5) arranged parallel to each other, and a stabilization rope (10) is arranged between the towers.
